RM2213   Hidalgoite

La Estrella mine, Pardos, Guadalajara, Castilla-La Mancha, Spain

Hidalgoite specimen from this classic Spanish mine. It appears as olive-green coatings, forming aggregates of tiny crystals. Collected in 1999 by M. Marí and A. García. The Estrella mine is located in the Majadillas hill, in the extreme south of the municipality of Pardos, in Guadalajara. It is an old copper and silver mine whose exploitation dates back to the 17th century, with its maximum activity being in the mid-19th century coinciding with the splendor of the nearby Hiendelaencina mines.

RM2185   Aragonite

La Pesquera, Cuenca, Castilla-La Mancha, Spain

Many specimens of aragonite are seen, as "pinecone" shape, also isolated, but this specimen has an "I don't know what" that makes it different for me. An elliptical "pinecone" of prismatic, divergent aragonite crystals, which are grouped around a central axis, with more developed crystals. Different and very aesthetic. A classic from Spanish mineralogy.


Size: 8.4 x 5.0 x 4.8 cm.
Found in 2012.

RM2074   Cinnabar

El Entredicho Mine, Almadenejos, Almadén, Ciudad Real, Castilla-La Mancha, Spain

This sample has, for me, both a collection and scientific interest. It is a sample of cinnabar "veins" in its host rock, which has been perfectly polished to be able to see the structures of this breccia. Intense red colors of cinnabar snaking between fragments of quartzite impregnated with cinnabar, isolated crystals of pyrite and veins of dolomite. A true curiosity from Almaden to study under the magnifying glass.


Size: 6.5 x 5 x 1.4 cm.

 

RM2050   Halite

Imón saltworks, Imón, Sigüenza, Guadalajara, Castilla-La Mancha, Spain

Very curious specimen formed by several cubic crystals of halite, some with hoppered growth forms, bright and translucent. A very aesthetic neoformation of these "salinas" (saltworks). Although it is believed that the Romans, in the s. I AD, they already extracted salt from the area, the saltworks of Imón were built in the 10th century and have been exploited intermittently for centuries. In 2015 they returned to production with the construction of new pools of enormous dimensions.
